EWSR1 and neoplasm: In view of the increasing prominence of EWSR1 rearrangement in soft tissue neoplasms, we evaluated the utility of FISH and RT–PCR as ancillary diagnostic tools in assessing potential EWSR1-rearranged neoplasms in today's current practice, and assessed the spectrum of EWSR1-rearranged neoplasms at our tertiary centre over the course of the establishment of the ancillary molecular diagnostics and molecular cytogenetics services.
